问题描述
我正在尝试将图表图像导出到PPT,即一张幻灯片中的每个图像,下面是我的代码
I am trying to Export Chart images to PPT i.e. each image in one slide, below is my code
String strTemplate, strPic;
strTemplate = "C:\\Program Files (x86)\\Microsoft Office\\Templates\\Presentation Designs\\Maple.GIF";
//strPic = @"C:\Users\rongala.ganesh\Pictures\arrow_left_green_large.png";
bool bAssistantOn;
Microsoft.Office.Interop.PowerPoint.Application objApp;
Microsoft.Office.Interop.PowerPoint.Presentations objPresSet;
Microsoft.Office.Interop.PowerPoint._Presentation objPres;
Microsoft.Office.Interop.PowerPoint.Slides objSlides;
Microsoft.Office.Interop.PowerPoint._Slide objSlide;
Microsoft.Office.Interop.PowerPoint.TextRange objTextRng;
Microsoft.Office.Interop.PowerPoint.Shapes objShapes;
Microsoft.Office.Interop.PowerPoint.Shape objShape;
Microsoft.Office.Interop.PowerPoint.SlideShowWindows objSSWs;
Microsoft.Office.Interop.PowerPoint.SlideShowTransition objSST;
Microsoft.Office.Interop.PowerPoint.SlideShowSettings objSSS;
Microsoft.Office.Interop.PowerPoint.SlideRange objSldRng;
//Create a new presentation based on a template.
objApp = new Microsoft.Office.Interop.PowerPoint.Application();
objApp.Visible = MsoTriState.msoTrue;
objPresSet = objApp.Presentations;
objPres = objPresSet.Open(strTemplate,
MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoTrue);
objSlides = objPres.Slides;
//Build Slide #1:
//Add text to the slide, change the font and insert/position a
//picture on the first slide.
objSlide = objSlides.Add(1, Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutTitleOnly);
objTextRng = objSlide.Shapes[1].TextFrame.TextRange;
// objTextRng.Text = "FAME Presentation";
objTextRng.Font.Name = "Comic Sans MS";
objTextRng.Font.Size = 25;
foreach (var ar in arr)
{
// ScriptManager.RegisterClientScriptBlock(this.Page,typeof(string),"alert"
objSlide = objSlides.Add(1, Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutTitleOnly);
objTextRng = objSlide.Shapes[1].TextFrame.TextRange;
// objTextRng.Text = "FAME Presentation";
objTextRng.Font.Name = "Comic Sans MS";
objTextRng.Font.Size = 25;
string[] str = (string[])ar;
strPic = str[0];
objSlide.Shapes.AddPicture(strPic, MsoTriState.msoFalse, MsoTriState.msoTrue,
150, 150, 500, 350);
objTextRng = objSlide.Shapes[1].TextFrame.TextRange;
objTextRng.Text = str[1];
objTextRng.Font.Name = "Comic Sans MS";
objTextRng.Font.Size = 48;
//Build Slide #2:
//Add text to the slide title, format the text. Also add a chart to the
//slide and change the chart type to a 3D pie chart.
//Build Slide #3:
//Change the background color of this slide only. Add a text effect to the slide
//and apply various color schemes and shadows to the text effect.
}
}
catch (Exception ex)
{
throw ex;
}
运行此命令时,localHost的所有操作均正常,但是当我托管此应用程序IIS7时,Throwing exception PowerPoint无法打开文件.所以我认为最好添加Response Header,所以我遵循以下代码
When I Run this, every thing is working fine in localHost, but when I host this application IIS7 it Throwing exception PowerPoint could not open file. So what I thought is better to add Response Header, so I followed the below code
dt
是数据表名称,其中包含当我单击SaveImage时保存的图像的路径
dt
is the DataTable Name which contains paths of the images saved when I click on SaveImage
GridView1.AllowPaging = false;
GridView1.DataSource = dt;
GridView1.DataBind();////////write this code only if paging is enabled.
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.ppt");///////for text file write FileName.txt
Response.Charset = "";
// If you want the option to open the Excel file without saving than
// comment out the line below
// Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.ppt";//for text file write vnd.txt
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite =
new HtmlTextWriter(stringWrite);
GridView1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
我可以在此处将图像添加到PPT中,但是它们在同一张幻灯片中,并且图像彼此重叠.
Here I can add Images to PPT, but they are in same slide, and the images are overlapping each other.
推荐答案
MS不支持在服务器上使用Interop(例如ASP.NET)-请参见
Using Interop on the server (like ASP.NET) is NOT supported by MS - see http://support.microsoft.com/default.aspx?scid=kb;EN-US;q257757#kb2
由于Windows Vista MS引入了几种与安全性有关的措施,这些措施可防止Windows服务执行类似于桌面的"操作……这意味着您必须规避几种安全性措施才能使其正常工作(不推荐!).
Since Windows Vista MS introduced several security-related measures which prevent a Windows Service from doing "desktop-like" things... which means you would have to circumvent several security measures to get it to work (NOT recommended!).
要在服务器场景中处理PPT,有一些选择(免费和商业):
To deal with PPT in a server-scenario there are some options (free and commercial) out there:
例如(一个商业选项是 Aspose.Slides ,它可以处理旧的(PPT)和新的(PPTX)格式.
A commercial option is Aspose.Slides which can handle old (PPT) and new (PPTX) format.
